c# - 远程服务器返回错误 : (416) Requested Range Not Satisfiable in C#

Question

我试过的代码:

string contents = string.Empty;

using (var wc = new System.Net.WebClient())
{    
   contents = wc.DownloadString("http://www.bizjournals.com/albany/blog/health-care/2015/10/what-this-local-bank-did-to-control-health-care.html");    
}

但是它的抛出错误

The remote server returned an error: (416) Requested Range Not Satisfiable

Answer 1

如果您的客户端未发送 User-Agent header ，某些网络服务器似乎可能会返回 416。尝试像这样添加 header :

wc.Headers.Add("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705");
